Abstract (en)
[origin: EP2827471A1] A power receiving apparatus (105) is provided with: a power reception unit (106) disposed at a distance from and opposed to a power transmission unit (104) of the power transmitting apparatus (101); a direct current (DC) voltage changing device (108) which constitutes one portion of a power receiving circuit configured to electrically connect the power reception unit and an electrical load (109) and which can change DC voltage supplied to the electrical load; and a controlling device (112) configured to control the DC voltage changing device to change the DC voltage to bring a current phase difference between current of the power transmission unit and current of the power reception unit close to 180 degrees when the electric power is transmitted and received between the power transmission unit and the power reception unit, the current phase difference corresponding to overall resonant frequency.
